I just picked that one as i could pick another. Meaning to say that images, even those carved not far from or even within the period may, or in fact, are less an evidence of facts than the author's imagination.
If you take the trireme, you then ought to acknowledge that there also were Mediterrnic monorremes, birremes, quadriremes and quinquerremes. Taking into consideration the presumption that each line of rowers of would need a different deck, imagine one of these ships with such a multi deck construction or, how long would the oars in the upper deck have to be to submerge into the water, besides considering that the different decks should have a reasonable distance between each other, to prevent the oars from getting tangled. A realistic reasoning is that what happened is that, there was only one row of oars, where two to five men would operate one oar, having inside the ship a number of pavements with different heights, with seats inclined towards aft ship, the lower one the thalamite, then the 'sigite', 'tranite' etc.
